Abstract

267,158. Akt.-Ges. Brown, Boveri, et Cie. March 6, 1926, [Convention date]. Cut-out arrangements; electromagnetic relays. -In order to obtain similar results in different parts of a network from relays of the same pattern which are connected to current and voltage transformers having different transformation ratios in the different sections, the voltage supplied to the several relay circuits is adjusted by auxiliary voltage transformers provided with tappings. These tappings are so arranged that they allow of any combination of percentages of units and tens of the total winding.
